WRENCH.

SPECIFICATION forming part of Letters Patent No. 458,337, dated August25, 1891.

Application filed May 15 1891. Serial No. 392,873. (No inodel.) I

Be it known that we, OSCAR L. DODGE and GEORGE T. DODGE, citizens of theUnited States, residing at Inwood, in the county of Queens and State ofNew York, have invented a new and useful Wrench, of which the followingis a specification.

This invention relates to improvements in wrenches; and the objects inView are to pro- Vide a cheap and simple construction of wrenchespecially adapted for use about marine engines or others employingglands located in inaccessible places.

Other objects and advantages of the invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the claim.

Referring to the drawings, Figure 1 is a perspective of a wrenchvconstructed in accordance with our invention. Fig. 2 is a plan of thesame in position upon a gland. Fig. 3 is a plan of the wrench,illustrating by dotted lines some of the various positions of the same.

Like numerals of reference indicate like parts in all the figures of thedrawings.

1 denotes the stock or shank of the wrench, and the same is tapered andotherwise shaped at its inner end to form a handle 2, while its oppositeend is broadened and rounded to form a head 3.

4L designates the jaw, the same being curved, as at 5, to conform to theshape of a gland, and terminating at its outer end in a cylindrical studor lug 6. The inner end of the jaw is broadened and terminates in arounded head 7, centrally pivoted by a bolt 8 to the head 3 of the stockand having its edge prothrown out of engagement with the teeth of thehead and said jaw may be swung forward so as to be thrown in variouspositions with relation to the handle or stock, or by swinging the jawto the rear other positions may be secured, and in this manner thehandle so disposed with relation to the jaw, or vice versa, as toreadily adapt the Wrench for use upon the glands inaccessibly located.Such glands are for the most part found upon marine engines, and hencethe wrench is especially adapted for this class of engines; but it willbe obvious that it may be used with the same facility and benefit uponany class of machines.

In use the cylindrical lug is fitted into one of the perforations 13 ota gland, as 14, and after being turned as far as the adjacent 0bstacleswill permit, the pawl engaging with the teeth, the handle is swung backto its first position or starting-point, the pawl riding over the teeth.When the pawl has traveled as far as the teeth extend, the lug isinserted into another opening and the operation repeated.

Having described our invention, what we claim is- In awrench of theclass described, the combination, with the stock 1,terminatingin thehandle 2 and head 3,01? the jaw 4, having the curved shank 5,terminating at its free end in a lug 6 and at its rear end in thetoothed or notched head 7, pivoted at 8 to the head 3, the pawl 11,pivoted between its ends at 10 to the head 3, and the spring 12, securedto the stock 1 and serving to press the pawl into engagement with theteeth or notches, substantially as specified.

In testimony that we claim the foregoing as our own we have heretoaflixed our signatures in presence of two witnesses.
